This isn't good enough for distros, who often pretend to be on one
kernel version yet have the driver backported from another.

This is hardly a stub for a backport.  It's a printk printing the
version.  At least 25% of drivers seem to do this (not that I entirely
approve ... it does tend to clutter the boot sequence a bit)

The whole reason for MODULE_VERSION() is to mark this correctly.
